First, when the fire truck arrives at the fire, it is first necessary to occupy a favorable position for fire extinguishing so that it can quickly enter the fire. Then, when the fire engine is driving on the fire, it is supposed to maintain a fast and safe state. It should be selected to be able to drive from the nearest fire engine aisle. When more vehicles are deployed together, each vehicle should be followed by a safe 80-50M distance. When they reach the fire, they cannot enter the same combat area together, so as not to hinder the on-site commanders from mobilizing vehicles and delay the timing of operations. 2. The driver of a fire engine should be obeying the command of the field commander on the battlefield, be flexible and resourceful, and perform all the commands of the on-site commander so as to smoothly ensure the smooth progress of the fire fighting. The fire in the scene of a fire is an irreversible change. It is also a direct threat to the safety of a fire vehicle. If it is a threat, the vehicle should be transferred to a relatively safe area before it can be performed again. Fight and need to report the parking position of the fire engine in time. 3. After the fire engine enters the fire, it must follow the position specified by the commander to stop. The parking posture of the vehicle is able to meet and satisfy the needs of the retreat and attack of the fire field, and it is possible to avoid the flexibility to freely prepare for the evacuation of the dangerous area at any time. The engine of the fire engine should be in a state where it must be in full operation. It cannot be turned off, delaying the timing of the fighting. When the vehicle is carrying out water supply, it should gradually start to increase the water pressure so as to avoid the fire fighting personnel being injured and the sudden explosion of the water belt under the adverse effect of the water gun, affecting the progress of the entire rescue work. Fourth, in the process of access to water, it should be noted that the fire hydrant water supply pressure can not meet the needs of the fire engine. When taking up the reservoir and the natural water source, it should be noted that the mud and water depth, etc., in order to be able to prevent too shallow depth of water and inlet pipe suction into the mud caused by the interruption of the water source of the fire scene. 5. If it is necessary to directly supply water at a relatively long distance from the fire, it is necessary to use the fire-fighting vehicle 's relay water supply method to supply water to the fire site. The driver of the water truck should notice that an overflow of the overflow pipe of the water truck can maintain an appropriate amount of water supply. When the rear vehicle has no way to pipe the overflow condition of the preceding vehicle, the driver of the preceding vehicle can open the entrance hole of the upper part of the vehicle's water tank so as not to prevent the rise of the tank due to the excess water supply. When water is supplied, the water tanker should choose to park in a place where the road conditions are relatively hard. If there is no way to park on a hard road, it is necessary to take a necessary measure to avoid the cause of overflow. This caused the vehicle to fall into a mud pit.
